SHUTTLE FOR LOOMS.

SPECIFICATION formingpart of Letters Patent No.64=5,695, dated March 20,1900.

Application filed July 18, 1899. Serial No. 723,663. (No model.)

'To to whom it may concern/.-

Be it known that I, ZEPHIRIN THUOT, a citizen of the United States,residing in Fall River, in the county of Bristol and State of Massachusetts,have invented certain new and useful Improvements in Shuttles forLooms, of which the following is a specification.

This is an improved shuttle which is con structed with a threadingdevice making a part thereof. In order tothread a shuttle, as after thethread has become broken, for instance, the ordinary method is to drawthe thread through the thread hole with the mouth by suction. This iscommonly called sucking it through. In some cases, however, an implementtermed a shuttlethreader is employed for grasping the thread and drawingit through the hole. In myimprovement the shuttle is provided with ameans whereby the thread may be guided to and drawn through the hole,such means being a part of the shuttle.

The nature of this improvement is fully described in detail below andillustrated in the accompanying drawings, in which- Figure 1 is a planview of a shuttle embodying my invention. Fig. 2 is a side elevation ofthe front portion or head of the same. Fig. 3 is a view, partly inlongitudinal vertical section and partly in side elevation, of the frontportion or head of the shuttle. Fig. 4 is a cross-section of theshuttle, taken through the slot P and showing the threading mechanism inelevation. Fig. 5 is a perspective View of the threading mechanismremoved.

Similar letters of reference indicate corre* sponding parts.

A represents the body of the shuttle, A being the head, and B is thebobbin sustained by a suitable spindle. The head of the shuttle isprovided with a suitable recess or well 0, into which is dropped a drumor barrel D. This drum is provided at its upper end with a flange E, anda screw F extends through a suitable vertical hole 6 into the bottom ofthe shuttle, thus securing the drum in the posi* tion shown. The flangeis circular in shape,

but has two segments thereof removed, thus leaving the straight edges Eand. E, the former resting against a corresponding edge A in the shuttleand in connection with the downward projection E, which extends into thenotch A in the shuttle, preventing the drum from turning therein. Fromthe lower portion of the rear side of the drum D a curved guiding-hornHextends upward, the upper end curving diagonally rearward or toward thebobbin, as shown in Figs. 1, 3, and 5. From the lower portion ofthefront side of the drum a short guiding horn or loop K extends upward,rearward, and toward that wall of the shuttle in which the thread-hole Lis situated.

After the thread has broken, to rethread the shuttle draw the end of thethread WV from the front rearward under the upper endof the guiding-hornH, thence swing it under the corner E of the flange E, and draw itaround the curved edge of said flange until itreaches the slot P, Fig.2, which extends through the wall of the shuttle andleads from the upperedge thereof under the flange to the thread-hole L. A further pull onthe thread will draw it down through the slot P into the thread-hole. Asthe thread is thus drawn down it passes down through a vertical slot R,formed in the wall A ,which separates the chamber in which thebobbinlies from the recess 0. The curved edge of the plate E is not incontact with the shuttle; but

'a curved space S is formed, through which the thread passes as it isdrawn around the plate to the drum itself. As the thread moves down theslot P it, as above mentioned, moves also down the drum and is thencaught under the guiding horn or loop K, and thus prevented from contactwith the. shuttle and catching therein, and guided to the threadhole L.Thus by simply catching the thread under the upper end of the horn H,drawing it under the corner E" of the flange E and around the curvededge thereof to the upper end of the slot P, and pulling on it thethread is safely guided into the thread-hole and the shuttle is quicklythreaded.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is--- 1. In a shuttle of the characterdescribed, the head of the shuttle provided with the vertical well orrecess 0 g the wall A separating said well or recess from thebobbin-chamber and provided with the vertical slot R 5 the vertical drumD secured to the shuttle within said well or recess and provided at itsupper end with the horizontal flange E of a partiallycircular form buthaving the straight edge E at one side thereof, said flange and shuttlebein g so formed as to allow of a space between the latter and thecircular edge of the former; the guiding horn or loop K extending upwardfrom the lower portion of the forward side of the drum and ofsubstantially the shape shown; and the guiding-horn H of the shape shownand described extending up from the lower portion of the rear side ofthe drum and into said slot R, the front wall of the shuttle beingprovided with the slot P extending from the upper edge thereof undersaid flange to the thread-hole, substantially as set forth.

2. In a shuttle of the character described, the head of the shuttleprovided with the vertical Well or recess 0 5 the wall A separating saidwell or recess and the bobbin-chamber and provided'with the verticalslo'tR; the ver tical drum 0 secured to the shuttle within said well orrecess and formed with the flange E substantially circular in shape butprovided with the straight edges E and E, the latter corresponding inshape with and fitting against the edge A making a part of the shuttie;the downward projection or rib E"forme on the under side of said flangeand extend ing into the notch A in the shuttle; and the horns R and Kextending respectively from the rearward and forward sides of the drum,said shuttle being provided with the slot P extending from the upperedge thereof to the thread-hole and being formed with the curved space Snext the curved edge of said flange,- substantially as described.
